Specification of Letters Patent.

Patented Aug. 1, 1905.

Application filed February 5, 1904. Serial No. 192,141.

To all whom it may concern.-

Be it known that I, CHARLES A. BAILEY, a citizen of the United States, residing at Cromwell, in the county of MiddleseX and State of Connecticut. have invented a Cartridge, of which the following is a full and complete specification.

flhis invention is an improvement in cartridges, and relates more especially to the class of paper-tube cartridges.

The primary object of the invention is to provide a cheap, simple, and etfective means for connecting the paper tube securely to the metal cap, so that the said tube can neither turn in the said cap nor pull out of the same.

A further object of the invention is to so construct such connecting means as to provide for reinforcing the breech of the cartridge.

Other objects and advantages of the invention will appear in the following specification, and what I claim as novel, and desire to secure by Letters Patent, is more specifically set forth in the appended claim.

In the accompanying drawings, Figure 1 is a longitudinal sectional view of a paper-tube cartridge constructed in accordance with my invention. Fig. 2 is a sectional view on line 2 2, Fig. 1. Fig. 3 is a detail view of the metal lining or breech-piece. Fig. 4 is a view of a modification showing a different arrange ment for the primer.

Similar letters of reference indicate similar parts in all the views of the drawings.

Referring to said drawings, and particularly to Figs. 1, 2, and 3, the letter A designates the metal cap, B my improved metal lining or breech-piece, and C the paper tube, which latter is located within the metal lining and is adapted to be connected thereto in the particular manner hereinafter described.

In carrying out my present invention the metal lining or breech-piece B is made cupshaped, as shownin Fig. 3, and the sides are cut away to provide dovetailed openings or recesses 5, between which are correspondingly-shaped projections Z). The object of these openings is to receive portions of the paper tube which are forced therein in assembing the parts, and the particular shape of the openings provides that the said portions will practically lock the parts together and prevent them from being pulled apart longitudinally. This is accomplished by having the edges of the openings disposed at an inclination; but obviously the same result could be attained by openings of various other shapes, it being essential only that the edges of the openings be opposed to a direct pull on the paper tube, and therefore the edges of the openings may be curved instead of straight. v

In assembling the parts the metal lining B is placed in the metal cap A and expanded with the same to provide the usual rim-flange a, after which the paper tube G is inserted and expanded out into the openings 7) in the metal lining. In some instances, as showirin Fig. 1, the lower end of the paper tube is expanded into the rim-flange during the operation of connecting it to the lining. In this manner the parts are securely and firmly connected and the breech of the cartridge strongly reinforced.

To provide a seat for the primer, the central portion of the breech of the cartridge is formed with a countersunk opening a, the walls of which are composed of the cap A and metal lining B, which are together spun inward, as in Figs. 1 and 2, while in the modiiication, Fig. 4, the primer-seat c is in the metal lining, as (1, alone, and the end wall of the metal cap, as f, is left intact, so as to provide a gas-tight construction.

As heretofore stated, the metal lining in ad dition to holding the paper tube in place also reinforces the breech of the cartridge; but in some instances it may be found desirable to further strengthen the breech of the cartridge by the employment of the ordinary breech-block.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In a cartridge, the combination with. the metal cap A, of a metal breech-piece 0 con nected to said cap by means of the rim-flange and provided with dovetailed projections 7) forming intermediate dovetailed openings Z), said breech-piece being located within the cap against the inner side thereof; together with a paper tube inserted in the metal cap and breech-piece and expanded into the dovetailed recesses of the latter, whereby the CHARLES BAILEY dovetailed projections are embedded in said Witnesses:
